[0017] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings, in which the same reference numerals represent the same or similar components having the same function.

[0018] In this document, "schematic" means "serving as an example, illustration or description", and any drawing, embodiment described as "schematic" in this document should not be interpreted as a more preferred or more advantageous technical solution. In order to make the drawings simple, only the parts related to the present exemplary embodiments are schematically shown in the drawings, which do not represent the actual structure and true scale of the product.

[0019] In one embodiment of the present application, as shown in Figure 1 , a bottle cap is provided, which comprises a lower cap 10, an upper cap 20 and a safety buckle 30. The lower cap 10 has a buckle end. A recess 11 is formed on the buckle end. An assembly end detachably assembled with the bottle mouth is formed on the lower cap 10 away from the buckle end.

[0020] As shown in Figure 1 , the upper cap 20 is rotatably arranged on the lower cap 10 along a rotation axis, so that the upper cap 20 can be rotated from a first position away from the buckle end (as shown in Figure 1The position of the top cover 20 shown) after rotation is in a second position that can be fastened to the fastening end (as shown). Figure 2 (The position of the upper cover 20 shown in the figure). A drinking spout 16 is formed at the top of the upper cover 20 at the position shown in the figure, so that drinking can be done through the drinking spout 16 after the upper cover 20 is opened. The connection between the lower cover 10 and the upper cover 20 is made of a flexible connecting plastic sheet 50, so that the upper cover 20 can be flipped up from the lower cover 10.

[0021] like Figure 2 , 5 As shown in Figure 6, the safety buckle 30 has an extending direction. Both ends of the safety buckle 30 along this extending direction are connected to the lower cover 10 and the upper cover 20, respectively. The connection points between its two ends and the upper cover 20 and the lower cover 10 are surface connections, as shown in Figure 6. Figure 8 As shown, multiple connection points 36 are arranged circumferentially along the safety buckle. There can be three connection points as shown, or two or more. A void structure 37 exists between two connection points 36. The safety buckle 30 includes a connection point in its middle extending direction. The cross-section of the connection point is smaller than the cross-sections at both ends of the safety buckle 30, so that when the upper cover 20 rotates from the second position to the first position, the connection point of the safety buckle 30 can break (e.g., ...). Figure 3 (As shown in the diagram). The safety buckle 30 is made of a fragile material with a designed elastic deformation. Specific materials can include PP, PE, PC, ABS, etc.

[0022] like Figure 2 In the middle, before the fixing ring 31 and connecting post 32 of the safety buckle 30 break, the fixing ring 31 of the safety buckle 30 is located Figure 2 The position of A in the middle. For example... Figure 3 As shown, when the upper cover 20 is flipped up along direction C, and when the safety buckle 30 breaks, the fixing ring 31 of the safety buckle 30 will fall into the bottom of the recess 11 in the lower cover 10 after it is separated from the connecting post 32, that is, it will move from position A to position B, while the upper part of the safety buckle 30 will remain in the upper cover mounting hole 21 of the upper cover 20.

[0023] Therefore, as Figure 4 As shown, area 23 of the upper cap and area 15 of the lower cap can be made of transparent plastic. Therefore, after the cap is opened, the retaining ring 31 will fall into the corresponding area 23 of the upper cap and area 15 of the lower cap. If the user sees the retaining ring 31 in area 23 of the upper cap and area 15 of the lower cap, it means that the upper cap has been opened. To make the user's identification more intuitive, the retaining ring 31 of the safety buckle 30 can be made of various colors, such as red, orange, or yellow. This allows the user to determine whether the bottle has been opened by judging the status of the safety buckle, making it easier to determine the bottle's open status.

[0024] like Figure 2 , 5As shown in Figures 6 and 8, in another embodiment of the present invention, the safety buckle 30 has a first fixing end and a second fixing end along its extending direction. The first fixing end is connected to the lower cover 10. The second fixing end is connected to the upper cover 20.

[0025] like Figure 2 , 5 As shown in Figure 6, the recessed portion 11 is a concave hole or an annular hole. A lower inner wall protrusion 12 is formed on the hole wall of the concave hole or on the outer side of the hole wall of the annular hole. The lower inner wall protrusion 12 has an arc-shaped surface or a straight surface in the direction facing the bottom of the concave hole or annular hole.

[0026] like Figure 2 , 5 As shown in Figures 6 and 8, the first fixed end is a fixing ring 31. The fixing ring 31 corresponds to the shape of the recess or annular hole so that the fixing ring 31 can be assembled into the recess or annular hole along the axis. Wherein, when the recess is an annular hole, an annular post 11 is formed in the center of the annular hole.

[0027] like Figure 2 , 5 As shown in Figures 6 and 8, a lower protrusion 34 is formed outward on the outer side of the fixing ring 31. The lower protrusion 34 has a lower stepped annular surface facing the second fixing end. The lower protrusion 34 has an outward inclined surface in the direction away from the first fixing end. When the fixing ring 31 is inserted into the concave hole or annular hole, the outward inclined surface of the lower protrusion 34 makes it easier for the fixing ring 31 to be inserted into the concave hole. When the top cover is opened, the lower stepped annular surface abuts against the arcuate surface or straight surface of the lower inner wall protruding ring 12.

[0028] like Figure 2 , 5 As shown in Figures 6 and 8, in another embodiment of the present invention, after the upper cover 20 and the lower cover 10 are fastened together, an upper cover mounting hole 21 is formed at a position corresponding to the recess 11 of the lower cover 10. An upper inner wall protrusion ring 23 is formed on the wall of the upper cover mounting hole 21. The upper inner wall protrusion ring 23 has an arc-shaped surface or a straight surface in the direction toward the bottom of the upper cover mounting hole 21.

[0029] like Figure 2 , 5 As shown in Figures 6 and 8, the second fixed end is a connecting post 32. The shape of the connecting post 32 corresponds to the upper cover mounting hole 21, so that one end of the connecting post 32 can be axially positioned within the upper cover mounting hole 21. The connecting post 32 can abut against the ring post 11, so that when the safety buckle 30 is positioned between the lower cover 10 and the upper cover 20, especially during the transportation of bottled water, because the ring post 11 supports the bottom of the connecting post 32 in the illustrated position, therefore, as shown... Figure 5As shown, the part of the connecting column 32 and the fixing ring 31 is not easy to produce pulling force, so that the connecting column 32 is not easy to separate from the fixing ring 31. At the same time, the ring column 11 is also more conducive to the safety buckle 30 in the installation, and the connecting column 32 abuts against the ring column 11, so as not to be easy to fall off.

[0030] As shown in Figure 2 , 5 , 6, 8, the safety buckle 30 at the connecting column 32 can be provided at one end of the upper cover assembly hole 21. The upper protrusion 33 can be provided with an upper step ring surface in the direction of the first fixed end. The upper protrusion 33 away from the direction of the first fixed end is an outwardly inclined inclined surface, and when the connecting column 32 is assembled in the upper cover assembly hole 21, the upper step ring surface is abutted to the arc surface or the straight surface of the upper inner wall protruding ring 23.

[0031] Therefore, when the lower cover 20 is turned over from the lower cover 10, the fixing ring 31 and the connecting column 32 cannot be separated from the fixing ring 31 and the upper cover assembly hole 21 under the action of the lower protrusion 34 and the upper protrusion 33, the connecting column 32 is torn off, and the fixing ring 31 falls into the bottom of the annular cavity. At the same time, due to the action of the lower protrusion 34 and the upper protrusion 33, the fixing ring 31 and the connecting column 32 are prevented from falling outwards.

[0032] As shown in Figure 2 , 5 , 6, the outer peripheral surface of the other end of the connecting column 32 is connected to the inner wall of the fixing ring 31 by a connecting piece. The connecting piece is uniformly or non-uniformly arranged along the outer peripheral surface of the connecting column 32.

[0033] As shown in Figure 2 , 5 , 6, in another embodiment of the present application, the connecting piece is one connecting piece or a plurality of connecting pieces. The intersection of the connecting piece and the fixing ring 31 is a variable cross section, a circular cross section or an elliptical cross section.

[0034] As shown in Figure 2 , 5 , 6, when the connecting piece is a plurality of connecting pieces, the plurality of connecting pieces are arranged at intervals of 120° around the outer peripheral surface of the connecting column 32. The cross section of the connecting piece gradually decreases from the connecting column 32 to the inner wall of the connecting ring. The connecting piece is inclined in the direction of the second fixed end.

[0035] In another embodiment of the present application, the bottom of the upper cover assembly hole 21 is a plane or an arc surface. The end of the connecting column 32 opposite to the upper cover assembly hole 21 is a plane or an arc surface corresponding to the bottom of the upper cover assembly hole 21. A tapered hole is formed at the end of the connecting column 32 towards the ring hole. The tapered hole can abut against the central region of the ring hole. The central region of the ring hole is a plane or an arc surface.

[0036] In another embodiment of the invention, the upper cover 20 and the lower cover 10 have an opening / closing side. The upper cover 20 has an opening protrusion on the opening / closing side. The opening protrusion includes an abutment surface that can face towards the lower cover 10.

[0037] In another embodiment of the present invention, the lower cover 10 may form a drinking hole 16 at one end facing the upper cover 20. The portion where the wall of the drinking hole 16 meets the opening forms a sealing wall.

[0038] The upper cover 20 includes a top cover end facing away from the lower cover 10. The outer surface of the top cover end forms a top cover surface. A protruding plug 22 is formed on the top cover surface in a direction that allows it to face the lower cover 10. The protrusion direction of the plug 22 is perpendicular to the top cover surface. The outer circumference of the plug 22 includes a first sealing annular surface.

[0039] When the upper cover 20 is fastened to the lower cover 10, the first sealing ring surface of the plug 22 can abut against and seal against the sealing hole wall, so that the plug 22 seals the opening of the drinking hole 16.

[0040] like Figure 7 As shown, in another embodiment of the present invention, the bottle cap includes a flexible wrapping ring 13 extending into the orifice in a direction opposite to the orifice wall. The flexible wrapping ring 13 gradually decreases in diameter from the orifice into the orifice. The flexible wrapping ring 13 is achieved through a thin plastic layer (the thinner the flexible plastic, the easier it is to deform).

[0041] like Figure 7 As shown, a second sealing ring 14 is formed on the direction where the stopper 22 is adjacent to the first sealing ring surface and away from the top cover surface. When the upper cover 20 is fastened to the lower cover 10, the flexible wrapping ring 13 wraps around and seals the ring surface of the second sealing ring. This results in a better seal for the bottle opening.

[0042] The opening of the drinking hole 16 is inclined inwards to form an inclined opening surface. The outer circumference of the seal forms an opening step surface corresponding to the inclined opening surface. When the upper cover 20 is fastened to the lower cover 10, the opening step surface can abut against the inclined opening surface to form a seal.

[0043] In another embodiment of the invention, a top recess is formed on the top cover surface at a position corresponding to the seal 22. The top recess has an inner annular cavity. A top convex ring is formed within the inner annular cavity.

[0044] The bottle cap also includes a top cap seal 40, which includes an outer peripheral surface. A sealing protrusion 41 is formed on the outer peripheral surface. The top cap seal 40 is detachably disposed within a top recess such that the outer peripheral surface of the top cap seal 40 can be opposed to the inner annular cavity and the sealing protrusion 41 and the top protrusion 25 are pressed together to form a sealing annular surface.

[0045] In another aspect of the present application, there is provided a bottle comprising a mouth adapted to be fitted with the fitting end of the bottle cap of the present application.

[0046] It should be understood that although the present specification is described in terms of various embodiments, each of which describes only one independent technical solution, the present specification is merely for the sake of clarity and those skilled in the art should consider the present specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0047] The above detailed description of a series of specific embodiments is merely for the feasibility of the present application, and is not intended to limit the protection scope of the present application, and any equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
